Building insulation system

ABSTRACT

A building insulation system for roofs and walls supported from the interior side of the building, which eliminates thermal bridges and bottom side ceiling fasteners to support the insulation system materials during the insulation and exterior sheeting process of the building construction. The insulation system creates an air gap space layer in roofs and in walls between the exterior wall and roof sheeting panels and the interior sheet material, which supports the insulation material layer. An air gap space enables active solar energy collection and its use to reduce the overall purchased energy for operation of the building. The insulation system preferably includes a support sheet material, a sheet material tensioning devices, an insulation material layer, insulation hanger retention devices, heat and air collection and distribution ducts, dampers, louvers, pipes, dehumidification and condensate collection devices used in the air gap layers of the building to improve the building energy efficiency.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to energy efficient buildingsand more specifically to a building insulation system, which providesbetter insulating properties than that of the prior art and whichremoves humidity typically trapped in the walls, roof and insulation ofthe building.

2. Discussion of the Prior Art

A brochure MB304 published by the North American InsulationManufacturers Association (NAIMA) continuously since 1991 describes thestate of the art most typically used to insulate roofs and walls ofpre-engineered metal buildings. This type of building currentlyrepresents over 40% of all non-residential buildings of two stories orless built in the US each year.

No. 5,953,875 of Harkins discloses aslide-in building insulation system. U.S. Pat. No. 6,247,298 to Harkinsdiscloses a roof fabric dispensing device for insulation systems and airbarriers over the exterior plane of the building structural members.U.S. Pat. No. 5,968,311 is a device for installing a vapor retarder overthe purlins or joist to support insulation. U.S. Pat. No. 6,705,059 is arolled fabric carriage device for unrolling a vapor retarding fabricover the tops of purlins which is used to support insulation. U.S. Pat.No. 6,216,416 is a system for installing insulation over purlins. U.S.Pat. No. 5,921,057 is an apparatus for dispensing an insulation supportsheet over the purlins. U.S. Pat. No. 5,653,081 is a method for payingout an insulation support sheet for insulating a building roof over thepurlins. U.S. Pat. No. 4,222,212 is an insulated roof over the purlins.There are temporary buildings, which have a waterproof coverings overthe tops of framing members to form a roof covering and which arecommonly used for agricultural and storage purposes.

One common problem with the design of current buildings havingintegrated thermal insulation systems is the requirement for structuralfastening of the insulation support apparatus through the plane of theinsulation system. The “through-fastening” creates multiple thermalbridges, which reduces the building thermal performance up to fiftypercent. The most predominant methods used to insulate pre-engineeredmetal buildings from as early as the 1950s, until today is simplydraping the insulation over the exterior of the building structuralmembers for support, applying the exterior building sheeting directlyover the insulation and then applying the exterior sheeting attachmentfasteners through the exterior sheeting, through the insulation from theexterior into the underlying building roof and wall structural members.This method results in thermal bridging fasteners with a frequency ofabout one fastener per every ten square feet of exterior surface area orless.

A second common problem is that insulation products in building roofsand walls are sandwiched between the roof or wall structural members andthe overlying building exterior sheeting with compression of theinsulation thickness and its inherent loss of thermal performance whichresults from this compression. Placing the roof and wall insulationtightly against the exterior roof and wall sheeting panels blocks thesolar heat energy from being absorbed and radiated off the interiorsurface of the sheeting materials for any practical use. The solarenergy that hits the building roof and wall surfaces is lost from anypractical collection and use. At the same time, fossil fuel energy ispurchased to provide heating, cooling and hot water heating for thebuilding occupants and processes.

The third common problem of achieving energy efficient buildings is thatthe thermal insulation has traditionally been installed during the roofand wall sheeting process. Insulation methods which require theinstallation of fasteners from the interior during the integratedinsulation and exterior sheeting process are shunned by installers ofthese materials in favor of methods that simply compress the insulationbetween the roof and wall structural members and the roof and wallsheeting panels with only externally applied fasteners. Such methodseliminate the need for fastening from the interior side of the roof andwall structure during the insulation and sheeting process and thereforeare preferred by installers.

This practice severely limits the thermal performance of the buildingsto much less than the desirable economic insulation levels. Due to theinsulation thickness reductions and thermal bridging, building thermalperformance is much less than what is required to honestly meet theminimum installed thermal performance criteria set forth by the variousstate energy codes. The most common building insulation methods not onlycompress the insulation thickness by variable percentages, but alsothermally bridge the exterior conductive building sheeting surfaces tothe interior exposed thermally conductive surfaces of the purlins,joists and girts. These structural configurations maximize theuncontrolled heat transfer between the two thermally bridged surfaces onthe opposite sides of the thermal insulation layer and will frequentlyresult in seasonal condensation on the interior exposed buildingstructural members. The roof and wall structural members become very hotin the summer, when the heat is not wanted in the building interiorconditioned space and are cold in the winter, when the heat is wanted inthe building interior conditioned. Buildings that are thermally bridgedbetween through the thermal insulation with exterior exposed conductivesheeting materials and interior exposed conductive roof purlins or joistand exposed conductive wall girts result in the opposite seasonal heattransfer effect that is desired and major loss of heating energy.

The cold exterior surface temperatures in the winter typically float upand down crossing over the dew point temperature of the interiorconditioned air and also of the dew point temperature of the air trappedwithin the insulation of the roof and wall assemblies of the building.Fiberglass insulation is mostly air. This condition results incondensation of the water vapor that increases conductivity and reducesthe insulation thermal performance, which may result in permanentbuilding structural damage and may also interfere with the building use.If the condensed liquid water accumulates within the building roof andwall assemblies it may also result in dripping and damage to interiorbuilding contents.

Prior art like that disclosed in the Harkins U.S. Pat. No. 4,446,664invention uses a steel strap support system, which temporarily spansacross building bays with steel straps fastened at their ends and ofteninstalled in a woven mesh. A flexible sheet material is customfabricated to fit the designated building areas, referred to as buildingbays, with the absolute minimum of field seams except along the buildingbay perimeter beams, where there is no problem sealing the edges as theworkmen work on the top side of the rafter beams. The flexible sheetmaterial is spread out and clamped in position on the platform ofspanned support strapping and then fasteners are required to beinstalled through the steel straps and sheet material from the buildinginterior into the inside flange of building roof purlins or joist fromthe interior. This method requires approximately one interior appliedfastener for every 30 square feet of the building roof or wallstructures. Each fastener is a thermal bridge between the steelstrapping and the metal structure to which it is attached.

The invention of the U.S. Pat. No. 4,446,664 creates a defined space forinsulation to expand, which eliminates virtually all unwantedcompression of the insulation in the roof structures. This method alsocompletely isolates all-of-the highly conductive metal roof and wallpurlins or joist surfaces from direct contact with the interiorconditioned air. This system however requires the installation of thefasteners from the interior of the building during the integratedprocess of installing the insulation and the sheeting of the building'sexterior roof surfaces. The Harkins '664 patent, while much morethermally efficient than typical methods, is often avoided in favor ofmuch less thermally efficient insulation products and methods which donot require fasteners to be installed from the building interior duringthe integrated roof insulation and exterior roof sheeting process.

Another problem that occurs in metal panel sheeted buildings is seasonalcondensation problems in the wall and roof systems. This phenomenonbecomes particularly evident with metal-sheeted buildings because themetal panel temperatures change almost instantly with a change inexterior temperatures. Typically, water vapor within the buildinginterior conditioned space concentrates along with a natural heatgradient at the highest elevations within the building heated space. Theconcentration of water vapor in air is often measured and expressed asrelative humidity. The warmer the air mixture is, the more the weight ofwater, in vapor form, it can hold. Water vapor will condense on anysurface of the building structure it contacts, which is below its dewpoint temperature. The dew point temperature is the temperature at whichthe relative humidity of the air contacting the cooler surface willreach 100% relative humidity and begin depositing the excess water vaporas liquid water on that cooler surface. A similar phenomenon occurswithin an air mixture itself as it cools and this condensation manifestsitself as fog, dew, rain and other forms of precipitation.

In buildings, water vapor will migrate through the vapor retarders,through poorly sealed joints, through staple holes, through gaps, etc.and will condense on the interior surface of the exterior sheetingpanels when the exterior surface temperatures are below the dew pointtemperature of the air mixture within the insulation space of the roofand wall assemblies of the building. The typical preferred insulationmethods fill the roof and wall assemblies to the exterior sheeting andany moisture is trapped inside of the wall and roof assemblies. Themoisture may condense and may accumulate seasonally during coldtemperatures. This trapped water vapor and resultant liquid water willcause premature deterioration of the building roof and wall buildingcomponents and will shorten the useful life of the building if it can'tescape naturally. Many older metal buildings leak air or breathe throughthe eave and wall flashings and the unsealed wall panel joints due towind pressure differences. This breathing allowed much of the trappedwater vapor to escape, but at the expense of thermal insulationperformance. New energy code requirements for sealing all constructionjoints will essentially eliminate this typical water vapor escapemechanism resulting in a much greater potential for condensation andaccumulation of liquid water within these building roof and wallassemblies of the future.

Buildings that have the compressed thermal insulation, buildings thatattempt to fill the roof and wall cavities, buildings that havethousands of staple holes along uniformly spaced insulation facingseams, buildings that have substantially thermally bridged conductiveinterior and exterior surfaces, buildings that trap and accumulatecondensed water vapor within the insulated roof and wall assemblies, andbuildings which repel the free solar heat energy hitting its exteriorsurfaces require significantly greater heating and cooling equipmentcapacities, require excessive fuel piping, require excessive electricalwiring, require excessive service capacities and cost significantly moreto heat, cool and ventilate than would be required, if the abovementioned problems were solved.

Accordingly, there is a clearly felt need in the art for a buildinginsulation system, which provides the following useful advantages:

That creates a defined space of sufficient air volume and distancebetween the roof and wall thermal insulation layer and the conductiveexterior sheeting materials to achieve the economic insulation thicknessand air gap space to operably manage the intrinsic air mixture, the airflows within and the collection of solar heat from the adjacent heatabsorbing, conducting and radiating surfaces of the exterior buildingsheeting and of their thermally bridged roof purlins and wall girtstructural members.

That creates a continuous insulation layer without having structuralthermal bridging, nor having fasteners inserted through the insulationlayer to support itself. An insulation layer that is supportedcompletely from the interior side without the need for any fastenersinstalled from the interior during the integrated ceiling thermalinsulation and exterior sheeting process of a building.

That provides for the natural collection and concentration of heatenergy within defined air gap spaces created within the roof and wallassemblies, which heat can be actively collected from the defined spacesby one of several methods and used to reduce energy consumption for thebuilding, its occupants and related processes.

That provides for water vapor control within the defined roof and wallassembly spaces to concentrate the water vapor by natural means and toactively remove and collect the water from the roof and wall defined airgap spaces as required to minimize any damaging accumulation and allowthe simple collection and use of the clean water for various usefulpurposes.

That maximizes the absorption, collection and transfer of solar heatenergy hitting the exterior surfaces of the building and to actively usethe clean solar energy to reduce the consumption of purchased energy forthe building interior space conditioning and related use processes. Thecolors and the emissivities of the roof and wall exterior sheeting panelsurfaces can be selected to maximize solar energy absorption, transferand use of the free solar energy, as opposed to reflecting it back intothe external environment with it's value completely wasted, as iscurrently the predominant practice and also part of a growing trendknown as “cool roofs” and highly reflective, “low emissivity” surfacecoating.

That use an active heat collection duct and piping systems installed atoptimal locations within the defined air gap layers created within thewalls and roof assemblies as a source for concentrated heat to be useddirectly with air circulation and/or indirectly through the use of aheat exchanger system such as a water pumping and storage system withfan-coil heat transfer units, baseboard type heating radiators, or theuse of electric powered, refrigerant type of compressor driven electricheat pumps that collect heat from the pre-heated, pre-concentrated airwithin the solar wall and solar roof air gap layers in lieu of exteriorunheated ambient air as a source for the heat energy it collects andtransfers. Efficiencies of over 50 Btu's per watt are expected from thisnew solar heat pump building invention.

That would facilitate the collection, concentration and storage of theclean solar heat energy in water stored in insulated reservoirs for offpeak demand use for space heating and hot water production processes.Excess heat energy collected can be used to melt snow and ice off roofs,driveways, sidewalks, etc. to eliminate typical removal costs, savingequipment costs, time and additional energy. The relatively clean waterfrom snow and ice melting can also be collected, and recycled for manyuseful purposes.

That interconnects the wall solar energy air gap collection system tothe roof solar energy air gap layer collection system which willfacilitate the transfer of concentrated heat from the wall air gap layerto the roof air gap layer on demand. This heat transfer allows thebuilding roof to be kept free of snow and ice by using solar heat energycollected in the wall air gap layer to maintain the solar exposed roofabsorptive surface area exposed to direct solar energy to absorb themaximum solar energy possible.

That will use free solar heat from the solar wall collection system toeliminate ice damming on cold roof edges by keeping them free of iceaccumulation caused by chronic build-up of ice from very slow melt ofsnow and ice off the exterior roof sheeting due to thermal bridging fromthe interior conditioned space and through the compressed thermalinsulation.

That uses a subterranean air tubing and air conditioning system topre-condition incoming ventilation air in all seasons to save energy andto also to simultaneously remove water vapor from warm, humid, incomingair during the summer cooling season, thereby reducing both the latentand sensible cooling loads required to maintain the interior conditionedspace temperature and humidity at desired levels.

That simplifies the installation process and eliminates the requirementfor any fastening from the interior of the building during theintegrated process of installing the insulation support sheet material,the roof insulation and the exterior sheeting panels of the buildingroof.

That eliminates thermal bridging through the roof insulation to supportthe insulation layer.

That eliminates thermal bridging through the wall insulation layer forsupport of the insulation.

That reduces the need for energy for building environmental spaceconditioning to such a low level, that for practical investment paybackreduces the building life cycle cost to a degree that renewable energygeneration may be added to the building project so that it annuallyrequires a net total of zero or less purchased energy for typicalbuilding conditioning and lighting loads, excluding other user loads, ifany.

SUMMARY OF THE INVENTION

A solar heat pump building preferablyincludes a building, at least one air gap heat collection layer, atension supported flexible sheet material layer, a material insulationlayer retained by the sheet material, a plurality of air ducts, aplurality of air duct dampers, a plurality of heat collection pipes, andan active mechanical heat pump collection, concentration, transfer anddistribution system. The building is preferably a metal building, butother types of buildings may also be adapted for use with the invention.The typical metal building includes a plurality of rafter columns, aplurality of end columns, a plurality of girts, a plurality of girtclips, a plurality of rafters, a plurality of purlins, a plurality ofpurlin clips, a plurality roof panels, a plurality of wall panels, and aplurality of bolts, nuts, fasteners, flashings and sealants.

The plurality of rafter columns and the plurality of end columns areattached to a foundation to form a perimeter of the metal building. Theplurality of girts are retained by clips extending off the exteriorsurfaces of the rafter columns and by a plurality of girt clipsextending off the exterior surfaces of the end wall columns with girtsspanning between adjacent pairs of the plurality of rafter columns girtclips and between adjacent pairs of the plurality of end wall columngirt clips. The plurality of rafters are attached to a top of theplurality of rafter columns. Rafters are attached to the top of thebuilding corner rafter columns at the end walls and also are attachedbetween building corner rafters columns to the tops of a plurality ofthe end wall columns. The plurality of roof purlins are retained by aplurality of purlin clips extending above the exterior surface of theplurality of rafters. The plurality of ceiling sheet material supportstruts are retained spanning between, or over, adjacent pairs of theplurality of rafters.

The solar heat pump building roof system includes the exterior roofsheeting panels, a purlin structural support system, an air gap heatcollection layer, a material insulation layer, at least one insulationsupporting sheet material, sheet material support struts and eave insidecorner sheet material support struts. Each ridge sheet material supportstrut is attached spanning between adjacent pairs of rafters andsupported by the building rafters. At least one sheet material supportstrut is attached below a ridge of the building roof and defines theinside sheet material ceiling line below the ridge. Each sheet materialeave support strut is attached in an inside corner between two adjacentrafters/rafter columns and defines the inside corner of the ceiling andwall junction of the sheet material in the building. For ease ofinstallation a sheet material may extend continuously from a ridge sheetmaterial support strut around the outside of an eave support strut to atermination point at a floor of the building or alternatively to atermination point created between the floor and the inside cornersupport strut. The ceiling sheet material is attached at opposingtermination points with adhesive, a tensioning device or any othersuitable attachment devices and methods. At least one tensioning deviceis preferred for each sheet material to control and manage deflection ofthe sheet material within desirable limits.

Alternatively, the sheet material extends from the floor of one side ofthe building around the exterior of one inside corner eave supportstrut, over a ridge support strut, around the exterior of the oppositewall inside corner eave support strut and downward for attachment to thefloor on an opposing side of the building. Alternatively the ceilingsheet material may be terminated at an intermediate ceiling, eave orwall support strut. Intermediate support struts may be attached spanningbetween or over two adjacent roof rafters, between to adjacent raftercolumns or between two roof purlin clips or wall girt clips.

The ceiling material insulation layer is inserted between at least oneceiling sheet material and a bottom of the plurality of roof sheets andpreferably a bottom of the roof purlins with a air gap layer created tothe exterior side of the material insulation layer. A plurality of ventspacer blocks may be attached to the interior or exterior facing flangesof the purlins prior to installation of the exterior metal roof panels.The vent spacer blocks have vent holes to insure the heat and convectionair naturally flows between the roof air gap layer spaces betweenadjacent purlins within the solar heat pump building roof. The pluralityof thermally conductive metal roof panels are attached to the outersurface flanges of a plurality of the roof purlins. The building air gapheat collection layer is thereby created between an outer surface of theceiling insulation layer and the inside surface of the roof metalsheeting panels. The purlin clips on the rafters may be extended toprovide the desired distance for the ceiling insulation layer withoutcompression of the designed insulation thickness. The typical metalbuilding ridge cap may be used to complete the roof at the buildingridge but with less efficiency than the optional multi-vent. An optionalridge mounted multi-vent extends through a ridge of the roof and extendsany length of the roof desired by the designer. The ridge mountedmulti-vent replaces the typical metal building ridge cap and is locatedbetween two ridge purlins or at the high side of the building if thebuilding is a single slope building. The multi-vent provides heatcollection, heat concentration, heat transfer, ventilation,dehumidification, day-lighting and building management functions.

The solar heat pump building wall system preferably includes an exteriormetal wall panel, thermally conductive metal girts, an air gap heatcollection layer, vent spacer blocks on interior girt flanges, a firstexterior sheet material which is typically an extension of the ceilingsheet material, a material insulation layer, a second interior wallsheet material which covers the wall material insulation layer from theexposure to the building interior space, and a means of using theconcentrated heat within the air gap layer(s). The solar heat pumpbuilding end wall systems contain the same general components as a sidewall system. The solar heat pump buildings preferably include aplurality of inner girt vent spacers and may also include a plurality ofouter girt vent spacers containing a plurality of air vent holes toensure the natural concentration of heat energy at the top of the wallair gap layer and allow convection air flows between girt spaces withinthe wall heat collection air gap layer of a system. Solar collected heatrises naturally and concentrates at the highest points of the wall androof air gap layer(s) that it can achieve. A plurality of outer girtvent spacers may be attached to the exterior facing flanges of the girtsprior to installation of the exterior metal wall sheeting panels. Theinner girt vent spacers are attached to the interior facing flanges ofthe girts prior to installation of the first (exterior) sheet materialwhich defines the interior surface of the wall air gap layer.

A plurality of rigid formed insulation hangers are then attached to theinterior facing surface of the first (exterior) wall sheet material. Amaterial insulation layer is attached in substantial contact without theinterior-most surface of the first (exterior) wall sheet material usingthe pre-installed insulation hangers. The material insulation is impaledon the rigid formed insulation hangers designed for this purpose whichare completely supported by the exterior wall sheet material and notfastened to the building girts to eliminate thermal bridging to thematerial insulation layer. A top of each second (interior) wall sheetmaterial is securely attached to the ceiling sheet material, such thatit's outer surface is in substantial contact with an inner-most surfaceof the wall material insulation layer. A bottom of each interior wallsheet material is attached to floor with adhesives, tensioning device,or other other suitable attachment means, such that it contacts the wallmaterial insulation layer. The material insulation layer is therebysandwiched between the first and second wall sheet material layers. Thesolar heat collecting wall air gap layer is thereby created between aninner surface of the exterior wall panel and the outer surface of thefirst (exterior) wall sheet material layer

The solar heat pump building wall heat collection air gap layer ispreferably connected to the roof heat collecting air gap layer at theirintersection at the building eave area so that the concentrated wallheat may be naturally transferred to the roof air gap layer, preferablyon demand, by using a damper system at this junction, and the wall heatenergy therefore used to keep the building roof heat absorbing surfacesfully exposed to absorb solar energy by keeping the roof surfaces freeof snow and ice with free solar heat.

The plurality of wall ducts include side wall ducts and end wall ducts.The plurality of side wall ducts preferably include two side wall eaveline roof ducts, two side wall upper wall ducts, two side wall baseducts and two side wall subterranean air ducts. The plurality of endwall ducts preferably include two upper wall ducts and two end base wallducts. Each duct includes a rectangular (preferably square) tube, whichpreferably includes a plurality of air flow holes formed through thesides thereof. A damper strip slot is formed in all four sides toreceive a sliding damper strip. The damper strip also includes aplurality of air flow holes. The hole locations and hole sizes in thedamper strip are engineered to equalize the collection (intake) anddistribution (exhaust) of air flows evenly through the wall and roof airgap layers along the length of each duct to maximize the collection andconcentration efficiency of heat energy rising through the walls androof of the solar heat pump building. A damper strip actuation device isused to open and close the plurality of air flow holes of the variousair flow paths on demand by sliding the damper strips in a damper slotof a duct. Duct end caps are used to enclose the air streams between theends of duct sections as desired.

Each side wall eave roof duct is located at the top of the wall air gaplayer to communicate with the roof air gap layer. Each side wall upperwall duct is located immediately below a side wall eave roof duct andcommunicates with the wall air gap layer. The side wall eave roof ductsare capable of receiving outside air through its air flow holes or abranch duct which communicates the upper wall duct or with the outsideair. The side wall eave roof ducts are also capable of receiving heatand air through its air flow holes or a branch duct which communicateswith an upper side wall duct. The upper side wall ducts and upper endwall ducts collect heat energy and air from the respective wall heatcollecting air gap layers through the air flow holes which communicatewith the wall air gap layer below the respective upper wall ducts.

The side wall and end wall base ducts are at the base of the respectivewall heat collecting air gap layers. A wall base duct is locatedadjacent the wall sheeting panels, above the floor, with air flow holeswhich communicate with the wall air gap layer. A side wall or end wallbase duct is capable of receiving outside air through its air flow holesor a branch duct which communicate with the outside air. The side wallor end wall base duct is also capable of receiving interior space airthrough its air flow holes or a branch duct which communicate with theinterior space air. The side wall and end wall base ducts are capable ofsupplying air to the bottom end of the wall heat collection air gaplayer from either the outside air or the inside air or both, through itsair flow holes which communicate with the wall air gap layer. The airflows are preferably controlled by an active damper in a damper slot orin the branch duct, as applicable.

Two subterranean air ducts are located adjacent to the interiorfoundation walls at two opposite building walls, at or below floor leveland extend substantially the length of each respective opposing buildingwall. A wall subterranean air duct communicates with the interior spaceair through air flow holes or branch ducts. The opposite subterraneanair duct communicates with the outside ambient air through a branchduct, containing a damper and an internal, air stream mounted fanpowered by energy. A plurality of subterranean tubing is located below afloor of the building preferably at a depth of six to eight feet witheach opposing tube end connected to the opposing subterranean ductlocated near the floor adjacent to the opposing foundation walls of thebuilding. Warm outside air flowed through the plurality of subterraneanducts and subterranean tubing will be cooled by a cooler groundtemperatures during the cooling season. Outside warm humid air flowedthrough a plurality of the cooler subterranean ducts and subterraneantubes will be naturally dehumidified by the cooler earth groundtemperatures during the cooling season. Cooler air flowed through theplurality of subterranean ducts and subterranean tubes will be warmed bya warmer earth ground temperature during the heating season.

It is preferable that the plurality of subterranean ducts be orientedeither parallel to the ends of the building or parallel to the sides ofa building which are substantially opposite each other and the pluralityof the subterranean tube ends connect between the to opposing wallsubterranean ducts.

It is preferred that each subterranean tube be sloped to a low point andconnected to a common drain pipe to collect seasonal condensation andpipe it to run by gravity to a common collection reservoir for recyclingfor other uses.

The ridge mounted multi-vent device includes a plurality of vent modulesattached in series. The plurality of vent modules are connected to eachother end-to-end with any suitable attachment device or method such asinstalling bolts or screws. Each vent module includes a box unit. Thebox unit includes a vent base, two end walls, two side walls and two boxside flanges. The two end walls extend upward from opposing ends of thevent base and the two side walls extend upward from opposing sides ofthe vent base. A single flange extends outward from a top of each boxside wall. At least one opening is formed through each end wall to allowthe flow of air between adjacent modules. A hole may also be formedthrough each end wall to receive a heat collecting pipe apparatus. Thispipe apparatus would include pipe, heat collecting fins, condensationcollecting trough, joint connectors, support brackets and drain tubing.

The top and bottom covers include a cover portion and a pair of coverside flanges. The cover side flange extends from each side of the coverportion. A sealing material may be placed between the cover side flangesand the box side flanges. A sealing material may be placed between thecover ends and the box end panels. The cover is fabricated from amaterial, which is light collecting, light diffusing, lighttransmitting, light concentrating, light reflecting or opaque to light.The box unit may have side wall and end wall wall extensions with areadapted to make the overall height of the box unit fit the thickness ofthe building roof assembly to close any air leaks between the interiorspace air and the roof insulation and air gap layer.

Damper strip slots are formed in the box side wall panels to receive asliding damper strip similar to that of the wall ducts. A plurality ofair flow holes are formed through the box side wall panels within theslot. The damper strip includes a plurality air flow holes, whichgenerally align with the plurality air flow holes in the box unit sidewalls. A continuous damper strip may be installed spanning betweenmultiple multi-vent modules to be operated by a single damper actuator.The damper strip may be shifted in the damper slot with a damper stripactuation device to allow the air flow holes to be opened or closed toany degree by sliding a damper strip in the damper slot. The collectedsolar heat entering the multi-vent is naturally concentrated from theroof solar heat collection air gap layer of the roof on either side ofthe ridge or both. The solar heat collected in the wall air gap layermay be extracted at the top of the wall air gap layer or passed onupward into the roof solar heat collection air gap layer to be carriedfurther upward and concentrated below the ridge cap or in the multi-ventfor extraction for direct use as heated air, for extraction for indirectuse by a heat absorption pipe of a heat pump for space heating, forheating process water, for the generation of power, for other usefulpurposes or may simply be exhausted to the atmosphere to cool thebuilding roof.

The optional multi-vent forms a heat and air collection duct when joinedend-to-end which can be connected to an in-line branch duct containing apowered fan or to an air handler unit to efficiently move andconcentrate the solar heated air of the solar heat pump building air gaplayers for useful purposes, rather than simply wasted as is the currentstate of the art.

Accordingly, it is an object of the present invention to provide abuilding insulation system, which creates an air gap layer between theroof and wall thermal insulation layer and the conductive exteriorsheeting and framing materials to operably manage the intrinsic airmixtures, the heat and air flows and the collection of solar heat fromthe adjacent heat absorbing surfaces of the exterior building sheetingpanels and thermally bridged to conductive roof purlins and wall girts.
